HE'IHOD OF APPLYING LIQUID ANTISEPTICS.

Application filed July 19', 1919. Serial No. 311,947.

To all whom it may concern.

Be it known that I, LEWIS KEMPTON lt'ionrrr, a citizen of the UnitedStates, and resident of New York, in the county and State of New York,have invented certain new and useful Improvements in Methods of ApplyingLiquid Antiseptics, of which the following is a specification.

This invention relates to methods of ap-. plying liquid antiseptics, andit has for its object to provide an improved method under which theapplication can be made at high pressures in a more effective,convenient, simplified and economical operation effecting the pressuredischarge as an atomized spray.

My improved method is especially adapted to conditions related to theuse of a small hand spraying device for convenient service and operationby individual users in the application of antiseptics or medicinalsolutions under pressure to affected parts, and also in dental andanalogous practices where a simple and easily-handled medium is desiredfor the effective treatment of cavities or other parts by an antisepticor medicated atomized spray discharged under high pressure.

In the particular purposes to which my invention relates the commonmethod of applying antiseptics has been by the employment of an elasticbulb constituting a container for the liquid and operating by handcompression to forcethe antiseptic through an atomizing nozzle extendingfrom the compressible elastic bulb. These conditions arecomparativelyineffective, can produce only an intermittent spray, andare deficient inthe continuous and uniform and high degrees of pressure which are adesideratum in the application of antiseptics in the circumstances forwhich my improved method is adapted. The elastic compression-bulb meansis furthermore disadvantageous in that it employs rubber in contact withthe antiseptic solution and is not durable.

Other methods of applying antiseptics have involved the use of an airpump to supply air under pressure to the container and thus force theliquid contents thereof through the discharge nozzle, in whichcircumstances repeated operation of the air pump is essential tomaintain the requisite air supply and pressure conditions. In othera1r-pressure methods the a1r has been stored under pressure in areservoir andsup- Speciflcation of Letters Patent.

plied by action of control means from the reservoir to the container toforce the liquid contents thereof through the discharge nozzle, and inthese conditions the air must be pumped into the initial reservoir tosupply and maintain the requisite pressure,

therein. All such air-pressure methods involving the employment of pumpsand reservolrs and independent air-control mechanism require complicatedand comparatlvely expensive apparatus not adapted for service or use asa simple and conven ent and small and inexpensive hand device.

he disadvantages and inconvenient condltlons as just .setforth areobviated in my lmprove'd method, which enables the applicat on ofantiseptics by the em loyment of a simple and inexpensive hand eviceandis especially adapted to the requirements of ndividual users andconditions of convenience to produce the effective discharge of theantiseptic as an atomized spray and under high pressure without themanipulation or control of any auxiliary mechanism or devices forestablishing or maintaining an a1r-pressure supply.

In the accompanying drawings, I have shown one form of simple handdevice by improved method may be employed. v Figure l is a sideelevation showing the complete hand device constituting the con tainerand discharge means.

. Fig. 2 is a vertical cross-sectional view on the line 2-2, Fig. 1.

Figs. 3, 4 and 5 are detail cross-sections, on an enlarged scale,respectively on the lines 3-3, 4-4 and 5-5, Fig. 2.

Corresponding parts in all the figures are denoted by the same referencecharacters.

In carrying out the improved method which constitutes my presentinvention, the antiseptic liquid solution is placed in a container incombination with carbonic acid gas, the proportions of the antisepticbeing in suitable volume or quantity adapted to the size of thecontainer and the carbonic acid gas being in sufficient volume tocarbonate the antiseptic liquid to the desired degree of pressure. Thecharged carbonated antiseptic solutionis maintained in the containerunder normal hermetically-sealed conditions, and is discharged therefromin desired volume and pressure under the action of the carbonic acid gasby suitable I valve control. The discharged volume of carbonatedantiseptic liquid as it leaves the container is then converted into ajet within an outlet tube and the passage of the discharge jet underpressure is retarded in the tube, and simultaneously with the passageand retarding of the antiseptic converted jet in combination with andunder pressure of the carbonic acid gas it is deflected and atomizedwithin the tube and finally ejected therefrom at a terminal orifice intothe outer air in the converted form of an atomized antiseptic carbonatedspray.

My improved method thus enables the application of liquid antiseptics inan eifective, convenient and simplified operation under high pressuresin a continuous uniform discharge and in the form of an atomized spray,in. conditions in which the antiseptic solution is at all times readyfor discharge in the desired volume and under the desired pressurewithout the manipulation or control of any auxiliary means fore'stablishing or maintaining the pressure action.

I have illustrated herein a mechanism merely as a showing of one form orconstruction of simple hand device adaptable to the conditions of themethod of applying liquid antiseptics which is the subject-matter of mypresent invention, it being understood that the improved method is notlimited to nor dependent upon any specific or particular structuraldetails of the device employed. In the construction illustrated, 1designates'the body of the device, which constitutes the container andis preferably cylindrical and elongated vertically to provide a narrowand relatively-deep interior reservoir in which the liquid antisepticand carbonic acid gasis retained. The body reservoir or container is ofa construction which will be normallv hermetically sealed, having closedside walls, 6, a closed bottom, 7, and a closed top, 8, from whichlatter depends an outlet tube, 9, extending longitudinally within thereservoir chamber, 10, to a point near the bottom, 7, and open at bothits top and bottom ends, 11 and 12. The top 8 carries means forcontrolling the discharge of the liquid antiseptic under pressure fromthe hermetically-sealed container, which means comprises in general anormally-closed valve, means for operating said valve, and a dischargetube for retarding the pressure jet released by said valve andconverting it into an atomized spray. The discharge-controlling meanscomprises a tubular cap, 14, extending upwardly from the top 8 andhaving at its base an internal chamber, 15, into which the top end 11 ofthe tube 9 opens, and in which operates a valve-head. 16, carried'at thelower end of an upwardly-extending plunger-rod, 17, said valve-headbearing with relation to a'valve-seat, 18, at the top of the chamber 15.The plunger-rod is operatively guided in the ca 14, and its action iscontrolled by a suitably-disposed spring, 19, exerting 1ts tension tomaintain the plungerrod in normal position holding the valve 16 to itsseat, and by a lever or handle, 20, operatively adapted to depress theplunger-rod against the tension of the controlling spring and cause thedesired degree of operation of the valve 16.

The foregoing construction provides a simple,inexpensive and convenienthand device of light weight and of suitable contour and dimensions,especially adapted to the conditions of my improved method, and the mainparts may all be constructed of metal or other durable and non-pliablematerial which will not affect the antiseptic contents, the preferableconditions of structure being such that the top and cap-piece 14 and thebottom 7 can be conveniently separated from the body-container 1.

The outlet means, in the device as herein illustrated, comprises adischarge tube, 21, preferably having a detachable connection with thecap 14, which tube opens at its inner end-to a chamber, 22, within thecap and immediately above and opening to the desirable, in the class ofdevices for carrying out my improved method, that the dimensions of thesupplementary chamber 22 be such that its area under operativeconditions is very slight, and that the bore of the discharge tube 21 bealso of slight diameter, the relative size or dimensions of saidsupplementary chamber 22 and outlet tube 21 as shown in the accompanyingdrawings being magnified in scale for the purpose of clearerlllustration. These relatively small dimensions, to afford a very slightoperative area under the conditions of operation as related to mymethod, in which the discharge of the combined medicated and carbonatedsolution is effected, and the medicinal solution is applied, by thepressure action of the combined gas, serve to preclude an afterflow ofthe combined medicated and carbonated solution, when the valve controlis suddenly closed. after the valve is operated to shut off furtherpassage of the solution to said valve-controlled chamber 22, it beingdesirable. under the conditions afforded by my improved method for thedirect and v definite applicationof the combined solu-- of the valve.Within the outlet tube 21, Which extends laterally from the cap 14 ashort distance beyond the plane of the wall of the container'l, areprovided means for retarding the jet of antiseptic liquid forced by thepressure conditions of my improved method to said tube and forconverting the pressure jet into an atomized spray. Said conversion andretarding means, as herein shown, consists of a block-partition, 23,mounted Within the tube at a point a short distance from its outlet endand having an internal spiral channel, 24, of narrow diameter, extendingfrom a small orifice, 25, at the center of the inlet face of the block23, to a small outlet orifice, 26, adjacent the periphery of the outletface of the block. The pressure jet entering from the tube is thus"retarded and converted into a spirally-rotat- I do not desire to beunderstood as lim-- iting myself to the detail features of the method asherein illustrated and described, nor to any particular constructionsfor carrying out the method, but reserve the right to all suchvariations as are Within the scope of my invention and improvements asde- I fined in the terms of the following claims.
